LC-HVB-90V High-Temperature Vacuum Drying Oven, 90 L and 4000 W (CAT#: STEM-BC-3595-ZJF)

The LC-HVB-90V is a 90 L vacuum drying oven for medium-volume laboratory processing. It supports drying, baking, heat treatment, and dry-heat sterilization under vacuum. Reduced-pressure operation is suitable for oxidation-sensitive and thermally unstable products. The chamber can be filled with inert gas when protective processing conditions are required. Its 4000 W heating system operates from ambient plus 20°C to 350°C. The LCD temperature controller uses PID calculations to maintain stable heating performance. Power-loss memory, automatic restart, sensor checking, and audible and visual alarms improve operational reliability. This vertical V-series oven is supplied without a vacuum pump or vacuum-pipeline cooling assembly.
